Texas Instruments · Operational Amplifier · SOIC-8

LME49721MAX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Amplifier A output. Drives loads down to 600Ω (and 10kΩ to within 10mV of either rail); output current capability ±9.7mA typ, short-circuit protected.
2 -INA input Inverting input of amplifier A. Rail-to-rail input range (VSS − 100mV to VDD + 100mV); input bias current 40fA typ, input offset voltage 0.3mV typ.
3 +INA input Non-inverting input of amplifier A. Rail-to-rail input range (VSS − 100mV to VDD + 100mV); input bias current 40fA typ.
4 VSS power_in Negative supply / ground pin (V−). Total supply voltage VS = V+ − V− must be 2.2V to 5.5V (6V absolute maximum). Quiescent current 2.15mA typ per amplifier.
5 +INB input Non-inverting input of amplifier B. Rail-to-rail input range (VSS − 100mV to VDD + 100mV); input bias current 40fA typ.
6 -INB input Inverting input of amplifier B. Rail-to-rail input range (VSS − 100mV to VDD + 100mV); input bias current 40fA typ, input offset voltage 0.3mV typ.
7 OUTB output Amplifier B output. Drives loads down to 600Ω (and 10kΩ to within 10mV of either rail); output current capability ±9.7mA typ, short-circuit protected.
8 VDD power_in Positive supply pin (V+). Total supply voltage VS = V+ − V− must be 2.2V to 5.5V (6V absolute maximum). PSRR 103dB typ.
